44 Understanding the Agilent E1330B Digital I/O Module

Chapter 4

Using the Handshake Modes

Handshaking ensures correct transfer of data between devices. You must set
both the mode and the timing to establish correct handshaking. SCPI
commands support the following modes of handshaking:

LEADing Edge

TRAiling Edge

PULSe

PARTial

STRobe

NONE

These SCPI commands set the type of handshake mode used:

[SOURce:]DIGital:DATA

[:type]:HANDshake[:MODE] <

mode

[SOURce:]DIGital:HANDshake

[:MODE] <

mode

These SCPI commands set the timing of the handshake (where timing
applies):

[SOURce:]DIGital:DATA

[:type]:HANDshake:DELay <

time

[SOURce:]DIGital:HANDshake

:DELay <

time
